I am building an Ember app with a Rails 4 JSON back-end. I am using the 'ember-rails' gem which embedded the Ember dir structure into the Rails app--which I like. It also included EmblemJS which I saw in action in this tutorial: http://ember.vicramon.com/
My question surrounds whether Emblem is going to be around for awhile and concerning the wisdom of building an app with it. Is this something I will be happy I did a year from now or should I rip it out and stick with Handlebars and HTML?
As supplied by @steveax in the question's comment, Emblem will be supported when HTMLBars comes out. This suggests longevity for EmblemJS.
